摘要：

C2F6 monolayers physisorbed on graphite have been investigated by heat capacity and x-ray diffraction measurements. With increasing temperature, the adsorbate shows a sequence of three 2D solid phases, all of them having a triangular lattice, followed by the 2D fluid stale. One of the transitions belongs to the universality class of the 2D Ising model and is of a new orientational order-disorder disorder type. [S0031-9007(98)05379-4].
